Hi PaQ, so another thing that I'd need to decide about for UV packing is which things to target to pack together within the same texture rectangle.

The way I was thinking would be to do it at a solid level, like shrinking down the UVs for each surface within a solid so that each surface occupied its own little uv island of the full texture rectangle.

But I guess there are other possible ways to do it like pack everything within the same style to be within one texture rectangle.

Is there one particular UV grouping method that would stand out as being the best thing to target?
